GEORGE H. BENTON, OF METUQHEN, NEW JERSEY.

ALVE.

Metuchen, in the county of Middlesex and State of New Jersey, haveinvented a new and Improved Valve, of which the following is a full,clear, and exact description.

The invention relates to globe valves, and its object is'to rovide a newand improved valve, arrange to permit convenient and quick renewal ofthe valve disk without discarding the other parts, to allow regrindingin a simple and eifective manner and to prevent the packing from comingout of the stuffing box.

The invention consists of novel features and parts and combinations of,the same, which will'be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in which.similar characters of reference indicate corresponding parts in all theviews.

Figure 1 1s a sectional side elevation of the improvement; Fig. 2 is asectional plan view of the same on the line 22 of Fig. 1 Fig. 3 is asimilar view of the same on the line 3-3 of Fig. 1; and Fig. 4 is aperspective view of the valve disk.

The shell or body A of the globe valve shown in Fig. 1, is provided witha diaphragm or bridge B formed with a beveled valve seat C, arrangedbelow the top face of the diaphragm B, as plainly indicated in Fig.

1. The valve seat 0 is adapted to be engaged by a valve disk D ofleather, hard rub- .ber, metal or other suitable material and beveled atan angle of about 45, to be seated on the correspondingly beveled valve.seat C. The valve disk D is held on the under.

side of the carrier E provided with a depending threaded offset E"centrally engaging the apertured disk valve D, and on the said oll'- setE screws a retaining nut l against the under side of the valve disk D,to hold the latter in place on the carrier E. The valve disk D isprovidedat the top and preferably at diametrically opposite points, withupwardly extending lugs D engaging correspondingly shaped recesses Eformed on the under side of the carrier E, to hold the valve disk Dagainst turning on the carrier E.-

The stem or spindle G for moving the carrier '1] and the valve disk Dtoward and from the valve seat C, is provided at its lower endSpecification of Letters Patent.

with the usual flange G engaging a seat E formed in the top portion ofthe carrier E, and the said flange G is engaged by a retaining nut Hscrewing in the top of the carrier E, to allow the stem G to turn in thecarrier and to cause the carrier to move with the stem when the latteris moved axially. When it is desired to regrind the valve seat U, thenut 11 and the stem G are locked together by the use of a suitable inpassing through registering a ertures I 'and G formed in the nut H anthe stem G, as indicated in Figs. 1 and 3.

The stem G is provided with the usual threaded portion G", screwing in abonnet I held in place on the shell or bodyA by a "'union nut J, and inthe upper portion of the bonnet I is arranged a packing K engaged by apacking follower L fitted into the upper end. of the bonnet I and havingside-wise extending lips I] (see Figs. 1 and 2), engaging correspondinggrooves in the wall of the bore of the bonnet I containing the packingIL. A nut N screws on the upper end of the bonnet I and engages thefollower L, so as to move the latter downward against the packing K, itbeing understood that as the follower L is held against turning by itslugs L;

it is evident that the follower remains in position when unscrewing thenut N. Nhen the operator turns the handle 0 on the stem or spindle Gthen the valve proper is moved toward or from its seat C according tothe direction in which the handle 0 is turned. Now by arranging thevalve seat C in the manner described, that'is, below the upper latsurface of the diaphragm B, it is evident t v wire drawing or injury to.the seat is prevented by throttling the valve or hot steam striking theseat t.

Byhaving the valve disk D form I D and the seat (J can be readilyreground V as the disk D is not liable to turn owing to the lugs Dengaging the recesses E.

Having thus described my invention,I-

claim as new and desire to secure by Letters Patent:

' 1. A globe valve, comprising a shell pro in its top and provided witha central threaded offset and recesses in its under face,

offset and having a beveled face and lugs on -and a nut screwing intothe seat of the ing a beveled face and lugs on its upper face v engagingthe recesses of the carrier, a spindle upon the lower end of which thecarrier 1s idedwith a diaphragm having a valve seat intermediate of itsupper and lower faces, a carrier havingan internally threaded seatthreaded depending offset and recesses in its under face, a valve diskon the threaded its upper face engagingthe recesses of the carrier, anut screwing onto the offset, a spindle having a flange at-its lower endand a transverse opening adjacent to said. flange,

a valve disk onwthe threaded ofi'set and havloosely'mounted, and meansfor locking the stem to the carrier to cause them to turn together.

3. A globe valve provided with a valve proper, comprising a carrierhaving a threaded offset and recesses in its under face, an aperturedvalve disk enga 'n the said offset and having a beveled i ace, a nutscrewing on the said threaded oflset and engaging the said valve disk tohold the latter inplace on the said carrier, and lugs on the said valvedisk and engaging recesses in the said carrier to hold the valve diskagainst turning on the carrier.

In testimony whereof I have signed my name to thisspecilication in thepresence of two subscribing witnesses.
